Apple finally broke down and confirmed that Siri keeps your personalized data collected and stored on its servers whenever you ask her a question. A representative from Apple was quoted confirming the company keeps Siri data stored in the cloud for two years. Apple claims that the data it stores is anonymous and it’s only for two years. Other companies that collect data such as Google, Facebook and other telecommunications companies have a similar data retention policies in place.

Apple may keep anonymized Siri data for up to two years. If a user turns Siri off, both identifiers are deleted immediately along with any associated data.

Based on the information Muller provided, Wired’s Robert McMillan explains exactly what happens when you use Siri:

Whenever you speak into Apple’s voice activated personal digital assistant, it ships it off to Apple’s data farm for analysis. Apple generates a random numbers to represent the user and it associates the voice files with that number. This number — not your Apple user ID or email address — represents you as far as Siri’s back-end voice analysis system is concerned.

Apple “disassociates” your user number from any clip older than six months, also deleting the number from the voice file. What the company also does is keep these disassociated files for up to eighteen more months for “testing and product improvement purposes.”
